We tried out the Little gym...LOVED it but WOW, they're expensive!!! Any other places in the area who have classes for little ones who love to move?
SRAC Call SRAC in Smithfield. Smithfield Recreation. It's a huge facility with indoor swimming pool. They may have something.
you might want to try Rex Wellness Center (there's one next to Target @ White Oak). I'm not sure if their swim sessions are year round, but I know they do mommy & me swim classes. Also, DanceArt offers mommy & me dance lessons (more affordable than the little gym).
